Small and simple living

The bigger the home, the more resources it consumes 

Yes, your home is your castle. But it is also responsible for a big chunk of your material and carbon footprints. The production, transportation and installation of all the materials in your home have already used a lot of energy and created emissions, and the operating and maintaining — lighting, heating, cooling and waste management — constantly create more. The simple truth is that the bigger the home, the more resources it consumes. 

Could we settle for less space? Could tiny homes be part of the solution?

‘House Shadow’ is Professor Matti Kuittinen’s proof of concept for the potential of industrial circular economy in construction. It exemplifies simple and small homes as an alternative to traditional detached homes, which make up 64% of housing in the EU. 

53% of the weight of this tiny home is made up of reused products or recycled materials, with the remaining materials representing the lowest possible carbon sources. 

When compared to detached homes, tiny house Shadow requires 85% less materials and 43% less land per capita.
